Answer 2

That's false.  If they were exactly the same, there would be no reason to have two different names for the same substance.

We also know they're different because if you take a jar of Hydrogen and a jar of Oxygen, let them mix and then stick a match into the mixture, the mixture burns with a blue flame, then it explodes with a loud pop, and then water drips out of the flame.  Obviously they can't both be the same substance.
